ADD info.py /home/python_user/info.py

# build with something like
# docker build -t python-demo .

# to see current python version by running info.py

info.py

#!/usr/bin/env python

import os

print platform.platform()
print platform.python_version()
print os.getuid()

Thank you so much for this

My update.

FROM debian:buster-slim

RUN apt-get update
RUN apt-get install -y --no-install-recommends make build-essential libssl-dev zlib1g-dev libbz2-dev libreadline-dev libsqlite3-dev wget curl llvm libncurses5-dev xz-utils tk-dev libxml2-dev libxmlsec1-dev libffi-dev liblzma-dev
RUN apt-get install -y mecab-ipadic-utf8

ENV HOME="/root"

WORKDIR $HOME
RUN apt-get install -y git
RUN git clone --depth=1 https://github.com/pyenv/pyenv.git .pyenv

ENV PYENV_ROOT="$HOME/.pyenv"
ENV PATH="$PYENV_ROOT/shims:$PYENV_ROOT/bin:$PATH"
RUN pyenv install 3.8.6
RUN pyenv global 3.8.6

My Update for Ubuntu:

FROM ubuntu:16.04

ENV PYTHON_VERSION 2.7.10

#Set of all dependencies needed for pyenv to work on Ubuntu
RUN apt-get update \ 
        && apt-get install -y --no-install-recommends make build-essential libssl-dev zlib1g-dev libbz2-dev libreadline-dev libsqlite3-dev wget ca-certificates curl llvm libncurses5-dev xz-utils tk-dev libxml2-dev libxmlsec1-dev libffi-dev liblzma-dev mecab-ipadic-utf8 git

# Set-up necessary Env vars for PyEnv
ENV PYENV_ROOT /root/.pyenv
ENV PATH $PYENV_ROOT/shims:$PYENV_ROOT/bin:$PATH

# Install pyenv
RUN set -ex \
    && curl https://pyenv.run | bash \
    && pyenv update \
    && pyenv install $PYTHON_VERSION \
    && pyenv global $PYTHON_VERSION \
    && pyenv rehash

# Optional : Checks Pyenv version on container start-up
ENTRYPOINT [ "pyenv","version" ]

@mayhs19 Thanks for the ubuntu version

@mayhs19 Thanks for this. Helped me out a lot!

alpine version

FROM alpine:3.17

ARG PYTHON_VERSION=3.10

#set mirrors if you need
#RUN sed -i 's/dl-cdn.alpinelinux.org/repo.huaweicloud.com/g' /etc/apk/repositories

RUN apk update && apk add --no-cache \
    dpkg-dev dpkg gcc gdbm-dev libc-dev libffi-dev libnsl-dev libtirpc-dev  \
    make ncurses-dev openssl-dev patch util-linux-dev zlib-dev

ENV HOME="/root"

#ENV PYTHON_BUILD_MIRROR_URL_SKIP_CHECKSUM=1
RUN pyenv install $PYTHON_VERSION
RUN pyenv global $PYTHON_VERSION

test 3.6 to 3.12

for ubuntu 22, use the same ubuntu16, but add libncursesw5-dev
